4 Claims. 1

This invention relates to coating devices of the roller type which are particularly adapted for coating or printing continuous surfaces or applying designs, paint or ornaments on walls, ceilings, cloth, and other surfaces, and comprehends improvements in the structures of my prior applications Serial No. 241,004, filed August 9, 1951, now Patent No. 2,610,582, and Serial No. 280,553, filed April 4, 1952, now Patent No. 2,616,367.

It is the object of the present invention to provide a design roller attachment which can readily be applied to any conventional paint roller applicator, the attaching structure being inexpensive, quickly applied, and readily attachable, interchangeable and adjustable to suit circumstances and designs in accordance with the desires of the operator.

Another object of the invention lies in the easy and inexpensive conversion whenever desired of a conventional paint applicator roller to a paint feed roller used for feeding paint to a design applicator roller attachment.

Other features of'the invention will more clearly hereinafter appear by reference to the accompanying drawings forming a part of the specification in which like characters of referencedesignate the corresponding parts throughout the several views, in which;

Fig. 1 is a side elevation of the device;

Fig. 2 is a side elevation, partly in section, of the body of the clamp bracket;

Fig. 3 is a transverse section on line 33 of Fig. 1

Fig. 4 is an exploded perspective view showing the various parts of the assembly; and

Fig. 5 is a fragmentary end elevation of a modifled form of base of the clamp bracket and clamp plate with the shank in position.

In the present disclosure the applicator roll is illustrated by reference character A, and the coating roll at B. The applicator roll A is normally provided with a handle C which is spaced from and extends transversely of the medial portion of the applicator roll, as best shown in Fig. 1. The handle C is connected to and supports the applicator roll A by virtue of the connecting shank D which is offset at D by connecting portion D which extends laterally of the shank portion D to a point suitably spaced laterally of one end of the applicator roll A to the offset portion aforementioned. The offset shank D is bent inwardly at E to provide the shank extremity D which projects through and is connected axially of the applicator roll A. By this handle and shank structure the applicator roll A may be con- 2 veniently manipulated to perform its various functions.

For applying a-predetermined design or color, the applicator roll A is designed to be associated with the coating roll B and this association comprehends the use of the clamp bracket [4, forming the subject matter of the instant application. In order that the coating roll B may be adapted for association with the applicator roll A through the use of the clamp I4, the coating roll B is provided with a core 6 having an axial bore 1 through which extends the bolt 9, the threaded end of the bolt 9, as indicated at [0, being of such length as to project substantially beyond the bracket [4 with which it is connected. The projecting threaded end ill of bolt 9 is provided with a thumb nut l l and a washer l2 which are used to clamp the coating roll assembly to the bracket l4 and against the adjustable stop nut 13 as will more clearly hereinafter appear. The soft outer cylindrical pattern carrying sheet is indicated by reference character 8 and is removable with respect to the core 6. I v

The structure embodying the present inventive concept is primarily the clamp bracket [4 which includes a relatively wide base l4 and a relatively reduced neck portion l5, the latter being provided with an elongated, longitudinally extending slot 22 through which the threaded extremity H] of the bolt 9 is adapted to project and by means of the stop nut l3, washer I2 and the thumb nut II to be adjustably clamped thereto. The relatively widebase portion of the clamp bracket, indicated by reference character M, has its side faces relatively flat and one of these faces shown at 16-23 is formed with a deep groove of angular form adapted to receive and seat the angular portion E of the offset shank portion D The depth of the groove I6 may be sufiicient to totally receive beneath the surface of the bracket the shank portion E, as shown in Fig. 3, and in this structure the angular portion E of the offset shank is clamped in position by the clamp plate l8 which may be formed by stamping from sheet metal and provided with inwardly projecting flange, the latter being adapted to engage the outer adjacent wall of the base portion l4 of the clamp bracket. The clamp bracket of Fig. 3 is secured in position by the thumb screw [9 which is threaded in registering openings 2l24 which are formed in the base of the clamp bracket within the confines of the groove l 6, as best shown in Fig. 2, and in the clamp plate 18.

f pr ferred, the groove It may be of such a depth as to receive substantially one-half of the thickness of the shank portion E and in this event a clamp plate such as shown in Fig. 5 may be used. In this form the clamp plate is of substantially the same thickness throughout and is provided with a groove 25 corresponding to the groove l623 in the bracket, and of substantially the same depth, it being intended that the grooves in the plate and in the bracket shall register to provide a passageway suitable to'snuglyreceive the angular portion E'of theshank. The'same type of fastening is provided in the modification of Fig. 5, this fastening being the bolt I9, threaded through both the plate and the baserofithe clamp.

It will be obvious to one skilled'in'thetart that ,plest formcfiadjustmentof the coating rollgbut ialso;forming the simplest .form of -.connecting means between the coatingroll and'applicator .roll. To remove the coating roll the thumbnut H is unscrewed andthe rollmoved'to free the bolt from the elongated recess. Toadjust the coating roll with respect to the applicator roll, the thumb nut l i may be first loosened by turning tothe left and'the-stop screw [3 can then be shifted to such a .position as may be deemed advisable to properly position the coating roll with respect .to the applicator roll, To remove the attachment from the applicator :-roll, itis simply necessary to remove the screw 19 from the base of the clamp bracket. The removal of screw 59 permits the lifting .of the .plate 18 and-the release of the -bracketfromshank portionE.

The clamp bracket body.may.be made as asimple casting by any wellknown process .or;method and may be.made.of. any suitable..material,.such as aluminum, or otherwise. 'Thewclamp plate l8 .may .bemade. .ofssheetmetal .by .a simple stamping operation,..or a .casting. as..shown.. at I 8? .Otherwise, the parts for connecting thecoatingrollto the applicator roll are.conventionalandreadily available on the open market.
